A particular talent competition has five judges, each of whom awards a score between
0 and 10 to each performer. Fractional scores, such as 8.3, are allowed. A performer’s
final score is determined by dropping the highest and lowest score received, then
averaging the three remaining scores. Write a program that uses these rules to calculate
and display a contestant’s score. It should include the following functions:
* `void getJudgeData()` should ask the user for a judge’s score, store it in a reference
parameter variable, and validate it. This function should be called by main once
for each of the five judges.
* `double calcScore()` should calculate and return the average of the three scores
that remain after dropping the highest and lowest scores the performer received.
This function should be called just once by main and should be passed the five
scores.

Two additional functions, described below, should be called by calcScore, which uses
the returned information to determine which of the scores to drop.
* `int findLowest()` should find and return the lowest of the five scores passed to it.
* `int findHighest()` should find and return the highest of the five scores passed to it.
